Abstract (en)

The present invention concerns an electron accelerator comprising: (a) a resonant cavity (1) consisting of a hollow closed conductor (b) an electron source (20) adapted for radially injecting a beam of electrons (40) into the resonant cavity, (c) an RF system coupled to the resonant cavity and adapted for generating an electric field, E, to accelerate the electrons of the electron beam along radial trajectories, (d) at least one magnet unit (30i) comprising a deflecting magnet adapted for generating a magnetic field in a deflecting chamber (31) in fluid communication with the resonant cavity by at least one deflecting window (31w), the magnetic field being adapted for deflecting an electron beam emerging out of the resonant cavity through the at least one deflecting window along a first radial trajectory in the mid-plane, Pm, and to redirect the electron beam into the resonant cavity through the at least one deflecting window towards the central axis along a second radial trajectory, characterized in that, the resonant cavity is formed by: €¢ a first half shell (11), having a cylindrical outer wall of inner radius, R, and of central axis, Zc, €¢ a second half shell (12), having a cylindrical outer wall of inner radius, R, and of central axis, Zc, and €¢ a central ring element (13) of inner radius, R, sandwiched at the level of the mid-plane, Pm, between the first and second half shells, wherein the surface forming the outer conductor section is formed by an inner surface of the cylindrical outer wall of the first and second half shells, and by an inner edge of the central ring element.
